GAS-BURNER.

SPECIFICATION forming part Of Letters Patent No. 427,379, dated May 6, 1890.

Application filed March 10,1888. fierial No. 266,852. (No model.)

To all whom it may concern.-

Be it known that I, EUGENE F. TRENT, of Jersey City, in the county of Hudson and State of New Jersey, have invented a certain new and useful Improvement in Gas-Burners,

-a side elevation of a gas-burner embodying my improvement. Fig. 2 is a vertical section of the same. Fig. 3 is a plan view thereof, a certain air-distributer being removed. Fig. 4 is a view of a portion of a burn er of slightlymodified form embodying my improvement.

Similar letters of reference designate corresponding parts in all the figures.

fi A designates atube forminga central draft- B designates a gas-supply pipe extending upwardly within the draft-flue. At its upper end the gas-pipe B communicates with a horizontally-extending pipe B. The ends of the pipe B extend through the wall of the tube A and open upon the exterior thereof.

0 designates a shell forming the outer wall of the burner-tip for the burner, and also of a heating-chamber for the gas, the inner side wall of which is formed by the tube A. The top of this gas-chamber and the inner wall of the burner-tip are formed by a cap or cover D, which may be stamped up out of sheet metal. This cap is provided with a central aperture a, formed by a flange a upon the cap. The

cap is also provided with' a horizontally-extending circumferential flange a provided with perforations for the escape of gas at the point of ignition. When the cap D is in position, the flange (0 extends into and fits snugly within the upper end of the tube A, while the flange a comes into close contact with the upper part of the shell C. When the gas is ignited, the chamber becomes highly heated, thereby heating the gas entering the chamber and producing more perfect combustion.

I employ an air-distributer for air ascending through the central draftflue, comprising, as here shown, two portions J J The lower portion or J is cylindrical and perforated in this example of my improvement throughout its entire length. Its diameter is such that when it is in position it will fit snugly within the downwardly extending flange a on the cap D. The portion J of the distributer is conical or tapering from its upper towardits lower end and is perforated. Near its lower end it is provided with a circumferential downwardly-extending flange 1), adapted to fit snugly within the open upper end of the portion J.

G designates a deflector for the ascending air. This deflector is conical or tapers in manner similar to the portion J of the distributer. It has a closed lower end, and, as shown,its wall is approximately parallel with the wall of the portion J of the distributor, but a distance inwardly therefrom. The upper end of the deflector G is provided with a horizontally-extending flange,which,when the deflector is in position, fits snugly within the upper open end of the portion J of the distributer. It will be readily seen that the upper end of the distributer is closed. It is also to be observed that in this example of my improvement the lower end of the deflector extends to about the level of the burner-tip.

F designates a chi mney-gallery, comprising a ring f, adapted to fit snugly about the tube A, and spring-fingers e for retaining the chimney in place. In Fig. LI have a set-screw g, by which the ring f may be secured more firmly, if desired.

By using an air distributer and deflector such as I have described the flame is uniformly spread and the air caused to be thrown outwardly in uniform quantity and force against all parts of the flame.

It is well known that gas-burners become clogged by dirt and deposits from impure gas. Therefore it is obvious that by the construction herein'set forth, whereby the several parts are removable, the burner may be readily cleaned both inside and outside.

In Fig. 4: I have shown that the pipe B, instead of being within the tube A, may extend upwardly at the outside of said tube. In this case the pipe B is made of two sections which are connected with the gas-pipe B below the tube A, the gas-pipe B terminating below the tube.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In a gas-burner, the combination, with a tube forming a central draft-flue, of a burnertip, a removable air-distributer comprising a cylindrical portion, and a conical portion removably secured to said cylindrical portion, and a conical air-deflector wholly within the distributer having its sides parallel with the conical portion of the deflector, substantially as specified.

2. In a gas-burner, the combination, with a central draft-flue, of a burner-tip, an air-distributer comprising a perforated cylindrical portion and a perforated conical portion, the said parts being removable, and an air-deflector Wholly within the distributer and having its walls parallel With the conical portion of the deflector, substantially as specified.

3. In a gas-burner, the combination, with a tube forming a central draft-flue, of a shell upon the exterior of said tube and extending away from the sam e,whereby a heating-chamher is formed between the tube and the shell, and a cap or cover for the heating-chamber independent of the shell, having a horizontally-extended flange provided with perforations through which gas may issue to be ignited, substantially as specified.

4. In a gas-burner, the combination, with a tube forming a central draft-flue, a shell forming the outer Wall of the burner-tip and heating-chamber, and a cap having the gas-escape perforations, of an air-distributer comprising the lower cylindrical portion and the upper portion tapering from its upper to its lower portion, and a deflector having a taper corresponding to the taper of the distributer, and having a horizontally-extending flange fitting within the upper end of the distributer, substantially as specified.
